Specialists in Lacquering Aluminium Coils

insulax® PET

bobina-insulax-pet-introinsulax® PET is the designation of ALUCOAT for the lacquered foil intended to be used for the production of insulation structures for building (roofs, chimneys, among others). insulax® PET  our product to be used in the production of insulation for roof ridges and edges that is composed for a laminated aluminium-PET that provides a very good flexibility and that for a similar properties has a lower thickness of aluminium than insulax® RF. Moreover provides an excellent barrier for humidity, gas and U.V. light.

Advantages

  • Laquers have been specially designed by our technical department and provide an excellent resistance to weathering and UV light.
  • It can be laminated to other materials (foams, plastics, among others) in order to form very high performance insulation and barrier products.
  • Easy to shape, which do it the best election to special applications.
  • There is the possibility to incoporate the pre-treatment coating Alucoat® prelac that improves the corrosion resistance and the adherence of the lacquer over the aluminium surface.

Composition
